where vim sets the settings of the "sessions"

vim /root/.viminfo

vim /home/sysadmin/.viminfo

vim /home/nortel/.viminfo

How to edit the colors of the current color scheme:

1. Check the name of your current color scheme located at: /root/.vimrc or /home/usrname/.vimrc (attention come kind of aliasing ... )

set colorsheme=dark

2. Edit the current colorsheme

/usr/share/vim/vim63/colors/darkblue.vim

/comments

3. Pick a HEX number for the color of the comments you would prefer to have .. #40FF00 (google color table )

Ctrl-R Ctrl-F Enters the file under the cursor into the editor in you commend line (command mode).

Ctrl-R Ctrl-A Enters the text from the editor in you commend line (command mode).

Mappings

the keyboard shortcuts performing user defined commands which could be saved at the /etc/vimrc

map :bn! ---- Ctrl + Tab for switching to the next buffer

map :bn! :bd # --- Ctrl + F4 - for closing the current buffer

As most other *nix applications, you can also pause Vim with Ctrl-z, which will drop you back to the shell. When you're finished, you can resume Vim with fg. (This is a feature of the shell, not a Vim feature.)



Any UNIX command can be executed from the vi command line by typing an "!" before the UNIX command.
Examples:
":!pwd" - shows your current working directory.
":r !date" - reads the results from the date command into a new line following the cursor.
